The assumption of a possible valuable non-rigidity was a longshot, I have to admit.
The McLarens same wishbone is also curved but just slightly, the BAR one is trully banana-shaped. The manufacturing problems let alone keeping weight as low as possible in creating such a shape for a component, which has to be as rigid as possible solely for aerodynamic reasons, seems hard to believe.
Found the pic on the net.
Well this is way larger than in the magazine and solves it a bit, seeing the wishbone curving around the pushrod.
Obviously it's worth the effort to keep the front attachmentpoints as close to pushrod attachment as possible.
